“Sometimes when I take a photo, it looks grainy.”

“WHY?”

Digital Noise and how to fight it!

Digital noise is the POLKA-DOT EFFECT in images with long exposures or images shot at high ISO settings in low-light situations. What is an ISO setting?

ISO SettingsInternational Standards Organization (ISO)

a benchmark rating of the relative sensitivity of film

Higher ISO # = sensor MORE sensitive to light Lower ISO # = sensor LESS sensitive to light A TYPICAL ISO range is from:

100 - 200 - 400 - 800 - 1600 - 3200

Recommended ISO’s

Sunny: 100-400 Cloudy: 200-400 Indoors: 400-800 Low Light Indoors: 800-1600

These are just starting points that you can adjust from.

Problem

The higher the ISO settings, the more DIGITAL NOISE a picture may have

So, how does ISO affect the shutter speed?

The more sensitive the sensor is to light, the faster the shutter speed can be set. If your camera does not allow you to adjust shutter speed independently, you can usually manipulate it with ISO settings. Try it out!
